<p>
      The output produced by a test module is one of the major assets the <span class="emphasis"><em>Unit
      Test Framework</em></span> brings to users. In comparison with any kind of manual/assert
      based solution the <span class="emphasis"><em>Unit Test Framework</em></span> provide following
      services:
    </p>
<div class="variablelist">
<p class="title"><b></b></p>
<dl class="variablelist">
<dt><span class="term">All test errors are reported uniformly</span></dt>
<dd><p>
            The test execution monitor along with standardized output from all included
            <a class="link" href="testing_tools.html" title="Writing unit tests">testing tools</a> provides
            uniform reporting for all errors including fatal errors, like memory
            assess violation and uncaught exceptions.
          </p></dd>
<dt><span class="term">Detailed information on the source of an error</span></dt>
<dd><p>
            The <span class="emphasis"><em>Unit Test Framework</em></span> test tool's based assertion
            provides as much information as possible about cause of error, usually
            allowing you to deduce what is wrong without entering the debugger or
            core analysis.
          </p></dd>
<dt><span class="term">Separation of the test errors description (test log) from the results
        report summary (test results report)</span></dt>
<dd>
<p>
            The information produced during test execution, including all error,
            warning and info messages from the test tools, executed test units notification
            constitute the <span class="bold"><strong>test log</strong></span>.
          </p>
<p>
            Once testing is completed the <span class="emphasis"><em>Unit Test Framework</em></span>
            may produce a summary <span class="bold"><strong>test report</strong></span> with
            different levels of detail.
          </p>
</dd>
<dt><span class="term">Flexibility in what is shown in the output</span></dt>
<dd><p>
            The <span class="emphasis"><em>Unit Test Framework</em></span> provides the ability to
            configure what is shown in both the test log and the test report. The
            configuration is supported both at runtime (from the command line) and
            at compile time from within a test module.
          </p></dd>
<dt><span class="term">Flexibility in how output is formatted</span></dt>
<dd><p>
            The <span class="emphasis"><em>Unit Test Framework</em></span> provides the ability to
            configure the format of the test module output. At the moment only <a class="link" href="test_output/log_formats.html" title="Log formats">three formats</a> are
            supported by the <span class="emphasis"><em>Unit Test Framework</em></span> itself. However
            the well defined public interface allows you to <a class="link" href="test_output/logging_api/custom_log_formatter.html" title="Custom log format support">customize</a>
            an output for your purposes.
